A li tion fil d December 11 1905. Serial No. 291,195.

To all whom it may concern.-

Be it known that I, ASA F. BATCHELDER, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented certain new and useful Improvements in Electric Locomotives, of which the following is a specification.

In my prior application, Serial No. 265 ,240 I have shown an electric locomotive wherein the motor-armatures are mounted directly upon the driving-axles and the field-magnet structure includes portions of the locomotive-frame, together with pole-pieces supported by said frame in operative relation to the several armatures. In this arrangement the speed of the armatures is determined by the speed at which it is desired to operate the drivers, and variation of power 0. n be procured only by altering the dimensions of the motor arts within the restricted limits imposed. ases may arise in which it is desired to employ a greater power than can be obtained by means of armatures mounted directly upon the axles, even though ossible under the circumstances. This Increase in power may be secured without enlarging the dimensions of the motors by mounting the armatures independently of the axles and designing them to run at a higher speed than the speed of the drivers, the proper speed of the drivers being obtained through speed-reducing gearing.

' In one of its aspects the present invention may be considered as relating to improvements in the locomotive disclosed in my prior application, such that the motor-armatures are adapted to be geared to the driv ing-axles, while at the same time a fieldmagnet structure similar to that shown in my prior application may be employed.

Considered in other aspects the present invention comprises novel features of construction and arrangement of parts of a locomotive, to be hereinafter described, and particularly pointed out in the claims.

The present invention will be more fully understood from the following description thereof, taken in connection with the accompanying drawings, wherein- Figure 1 shows in side elevation a locoan end elevation of such locomotive, certain parts being broken away to more clearly show novel features of construction. Fig. 3 is a section taken transversely of the locomotive adjacent one set of drivers and the operating-armature associated therewith; and Fig. 4 is an enlarged side elevation of a portion of the locomotive-frame, showing the manner of supporting it u on the drivers.

Reference being had to t e drawings, 1 indicates a locomotive having drivers 2, a frame 3, and a cab 4, arranged upon the frame. The frame is supported in the usual manner through springs and equalizing mechanism 5, carried by yokes 6, which are in turn borne upon journal-boxes or bearing members 7. These parts may have any. usual or desired construction, except that,

the journalboxes or bearings members are made elongated, so as to provide bearings8 for the motor-armatures 9, and the frame is preferably made rather deep, so that the pedestals or guides 10 may extend-throughout the entire length of the journal-boxes or bearing members in order to maintain them securely in alinement. The armature-bearings are preferably located directly over the respective axles 11 and at some distance therefrom, so as to afford ample clearance for the armature. the journal-boxes inside of the driving- Wheels and to provide each of the armatureshafts 12 with two pinions 13, which mesh with gears 14, secured, respectively, to the inside of the corresponding driving-wheels. This construction and organization of journal-boxes and gearing forms a compact and balanced arrangement, but it is of course understood that the journal-boxes may be otherwise situated and the driving connections between the armatures and axles bealtered without departing from the present invention as viewed in some of its aspects. The pole-pieces 15 arepreferably supported upon cross members 16 of the frame, as in the construction shown in my prior application, although it is of course evident that a difierent arrangement of field-magnet struc.

ture may be employed without departing from the scope of the present invention.

I also prefer to arrange v 17, and 18 ,are additional masses of magnetic material carried by the locomotive frame-and arranged in the magnetic circuit of'the'field structure.

19 indicates diagrammatically a motor-generator set mounted directly upon the locomotive-frame or upon the members'17 and 18.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. In an electric locomotive, a drivingaxle, a locomotive-frame, bearing members journaled on said axle and supporting said frame, a motor having an armature revolubly supported by said bearing members, and a driving connection between said armature and said axle.

2. In an electric locomotive, a drivingaxle, a locomotive-fra111e, bearing members j ournaled upon said axle and supporting said frame, an electric motor having an armature journaled in said bearing members, and a driving connection between said armature and said axle.

3.

4. In an electric locomotive, a drivingaxle, a locomotive-frame, members journaled on said axle and supporting said frame, .an electric motor .having ,an armature j ournaled in said members above and-inalinement with said .axle, and a driving connection between said armature and said axle.

5. In ,an electric locomotive, -a drivingaxle, a locomotive-frame, bearing members journaled atone end upon saidaxle and .arranged to support-said frameat the other end an electric motor having an armature j ournaled in said bearing members at points intermediate the ends thereof, and ,a driving connection between said armature and said axle.

6. In an electric locomotive, a plurality of driving-axles, a locomotive-frame, bearing members on the several axles adapted to support said frame, motor-armatures journaled in said bearing members in operative relation to the axles, pole-pieces carried by said frame in operative relation to said armatures, and driving connections between the several armatures and axles.

7. In anelectric locomotive, a -locomotiveframe, a driving-axle provided with wheels at its opposite ends, bearing members journaled on said axle and adapted to support said frame, a motor havin an armature journaled in said bearing mem bers, and intermeshing gears located respectively on said wheels and a 4-; on-opposite ends'of file shaft of said armature.

8. Inanielectriclocomotive, a-locomotiveframe, a driving-axle provided with wheels at its opposite ends, bearing members journaled on said axle and adapted to support said frame, a motor-armature having its shaft journaled in said bearing members, intermeshing gears located respectively on said wheels and on opposite ends of said armature-shaft, and pole-pieces carried by said frame in operative relation to saidarmature.

9. ,In anelectric locomotive, a locomotiveframe, a driving-axle provided with wheels at its oppositeends, bearing members journaled on said axle intermediate said wheels and adapted to support said frame, a-motor having an armature-shaft journaled .in said bearing members, and intermeshing gears-lo cated respectively on said wheels and on opposite ends of the armature-shaft.

10. In an electric locomotive, a locomotiveframe, a driving-axle provided with wheels at its opposite ends, bearing members journaled at one end on said axle intermediate said wheels and supporting said frame atthe shaft.
